The Arctic - A New Region for China's Foreign Policy
Article is devoted to foreign policy of China in the Arctic. Main attention is paid to strategic view of the China concerning the Arctic, to bilateral and multilateral cooperation on the Arctic issues, also to opinion of Russian experts about discussing of Russian-China economic partnership. It was shown interests of the People's Republic of China in the Arctic: use Arctic transport system from the Pacific Rim to Europe; possibility of access to the Arctic resources; seeks of partners for the realized of Arctic projects and programs. It was pointed six directions of China cooperation in the Arctic: a) scientific researches, b) natural minerals, oil and gas issues, c) tourism, d) routes of the Arctic navigation, e) use of high technologies in development of regional economy, e) cooperation in the cultural and educational spheres. Authors are summarized that at the initial stage of the international cooperation in the Arctic polar scientific researches become as the tool of “he soft power”, and in the long term - the Northern Sea Route of the Russian Federation is included in the Strategy of China Economic belt and the Maritime Silk Route in the XXI century

Aqueous RAFT Synthesis of Glycopolymers for Determination of Saccharide Structure and Concentration Effects on Amyloid β Aggregation.
GM1 ganglioside is known to promote amyloid-β (Aβ) peptide aggregation in Alzheimer's disease. The roles of the individual saccharides and their distribution in this process are not understood. Acrylamide-based glycomonomers with either β-d-glucose or β-d-galactose pendant groups were synthesized to mimic the stereochemistry of saccharides present in GM1 and characterized via 1H NMR and electrospray ionization mass spectrometry. Glycopolymers of different molecular weights were synthesized by aqueous reversible addition-fragmentation chain transfer (aRAFT) polymerization and characterized by NMR and GPC. The polymers were used as models to investigate the effects of molecular weight and saccharide unit type on Aβ aggregation via thioflavin-T fluorescence and PAGE. High molecular weight (∼350 DP) glucose-containing glycopolymers had a profound effect on Aβ aggregation, promoting formation of soluble oligomers of Aβ and limiting fibril production, while the other glycopolymers and negative control had little effect on the Aβ propagation process
